to be sure, the mossad did issue several warnings to amreeka about 911 which were flatly ignored
however, it doesnt take too much imagination to see taht the post 911 regional transformation in that area is just as much (if not more) beneficial to israel than it is to amreeka
on the other hand, even more than zionism these guys are greedy, and tehy would happily put the israeli people at risk of attack to increase their profit margins
